Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface treatment apparatuses, such as upright vacuum cleaners, often lack reconfigurability and balance, leading to user fatigue and inefficiencies in cleaning operations.
Innovation Solution
A reconfigurable surface treatment apparatus featuring a removable pod that couples to a wand, with the pod containing a suction motor assembly cavity, a battery cavity, and a dust cup cavity, allowing for balanced distribution of components and improved maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the pod contains all major components (motor, battery, dust cup) in a integrated design, then the apparatus structure is simplified, but the center of gravity becomes difficult to balance causing user fatigue
Solution Approach 1:
The apparatus is divided into distinct segments: the pod containing major components (motor, battery, dust cup) and the wand handle. This segmentation allows independent positioning of weighty components in the pod while keeping the wand lightweight, achieving both structural integration and balance.
Solution Approach 2:
The pod serves as a counterweight element by concentrating heavy components (motor and battery) in a single location that can be strategically positioned. This creates a balanced center of gravity that reduces user fatigue during operation.
2Stability of the object's composition
If the pod is permanently integrated to the wand, then the apparatus structure is more stable, but the components cannot be easily separated for maintenance or storage
Solution Approach 1:
The connection between the pod and wand is made dynamic rather than fixed. The removable coupling mechanism allows the system to transition between integrated (stable during use) and separated (for maintenance or storage) states, providing adaptability.
Solution Approach 2:
The apparatus is designed as separable segments (pod and wand) that can be easily coupled and decoupled. This segmentation enables stable operation when connected while facilitating easy maintenance and storage when separated.
3Adaptability or versatility
If the pod contains all components including dust cup, motor, and battery, then the apparatus is more versatile, but the device weight increases
Solution Approach 1:
The apparatus is segmented into a pod containing all major components (motor, battery, dust cup) and a separate wand. This concentration of components in the pod achieves versatility while allowing the pod to be removed and stored separately, reducing the weight of the operating wand.
Solution Approach 2:
The heavy pod can be extracted and removed from the wand when not in use. This extraction reduces the operational weight of the apparatus during cleaning tasks while maintaining full functionality when the pod is attached.

AI summary
A reconfigurable surface treatment apparatus may include a wand and a pod removably coupled to the wand. The wand may have a first distal end that is configured to couple to a surface cleaning head and a second distal end that is configured to couple to a handle. The pod may include a suction motor assembly cavity, a battery cavity, and a dust cup cavity. The suction motor assembly cavity and the battery cavity may be disposed on opposing sides of a vertical plane, wherein the vertical plane extends along a central longitudinal axis of the pod. The dust cup cavity may be disposed between the suction motor assembly cavity and the battery cavity such that at least a portion of the dust cup cavity is disposed on each side of the vertical plane.
